Cannot convert composite to solid with thickness

[mwilliamsAYSQ2]

I have been trying to give this part a thickness for several days now, and I feel I have tried everything. I have patched and stitched repeatedly. I have repaired body several times.  I have been able to convert it to a solid one time but once I did I still couldn't give it any volume. Please help, as i have other parts just like this one giving me problems.

Can't do much without the derive part.

How can you have a "solid" without volume?

[mwilliamsAYSQ2]

As in it changed from a surface to a solid body in the model browser. What do you mean the derive part?

Can you request better quality geometry from the source?

[mwilliamsAYSQ2]

unfortunately I can't. This was a 3d scan project we went 4 states away for.

When I open the surface in repair environment and did a find errors, there is a modeling uncertainty... Looks like a wrinkle in the part:

I'm wondering if there are more like this?

Im gonna try to find all the uncertainties and delete those faces and try to patch them. Maybe less and smoother faces will help
